Abstract
Forty-four pairs of mother and 36-month-old child were closely observed while they were at make-believe plays, and the following results have been obtained on the mother's role regarding script structurization as well as the script structures and their characteristics. 1) Both children and mothers show all kinds of main slots regarding eating and drinking, but their appearance rates are not the same. 2) While children show a lot of slots regarding cooking, serving and putting away the utensil for safekeeping or future use, mothers show a lot of slots regarding meal time manner including a comment, “Tasty!” 3) In the slots regarding eating, mothers help get the scripts structures by utterance and/or response to their child's slots. Mothers still play an important role in the scripts regarding eating even with their 36-month-old children. 4) In the slots regarding drinking, it is suggested that children show development in script structurization as they chronologically integrate their slots for themselves.
